HEID, D. M.; SERRA, A. P.; DANIEL, O.; MATOS, F. A.; SALTON, J. C.; NOGUEIRA, I. M. B. N.; CREMON, T.; CARVALHO, R. P. de; BOTTEGA, S. P.Peltophorum dubium canbe an alternative of forestry species to be includedin integrated crop-livestock-forestry systemsin tropical region. The aim of thisresearch was to evaluate the performanceof P. dubiumunder intraspecific tree competition and cardinal directions to measure the possibility of introduction in integrated livestock-forestry systems.The experiment was performed in a Nelder Wheel competition, whi...
Agricultural management systems affect on physical, chemical and microbial soil...
LOURENTE, E. R. P.; SILVA, E. F. da; MERCANTE, F. M.; SERRA, A. P.; PEIXOTO, P. P. P.; FERREIRA, R. C. F.; ENSINAS, S. C.; NETO NETO, A. L.The purpose of this research was to assess the effects of replacement of native ?Cerrado? vegetation (NV) into croplands on soil chemical, physical and microbial properties. This research was carried out on a farm under Rhodic Hapludox soil with different types of agricultural managements systems, and it was used a NV to compare the systems. The experimental design was set up in completely randomized with five ...
Soybean agronomic performance in narrow and wide row spacing associated with NP...
ROSA, C. B. C. J.; MARCHETTI, M. E.; SERRA, A. P.; SOUZA, L. C. F. de; ENSINAS, S. C.; SILVA, E. F. da; LOURENTE, E. R. P.; DUPAS, E.The purpose of this research was to evaluate soybean agronomic traits performance under row spacing associated with NPK fertilizer. The experimental design was set up in a randomized complete block and the treatments were arranged with factorial concept, consisting of four NPK (02-20-18%) fertilizer rates (0; 200; 400 and 600 kg ha-1) and five row spacing (0.35; 0.45; 0.50; 0.60 and 0.70 m), with three replicat...
Cover crops affect on soil organic matter fractions under no till system.
ENSINAS, S. C.; SERRA, A. P.; MARCHETTI, M. E.; SILVA, E. F. da; PRADO, E. A. F. do; LOURENTE, E. R. P.; ALTOMAR, P. H.; POTRICH, D. C.; MARTINEZ, M. A.The purpose of this research was to identify the soil organic matter (SOM) fractions changes in a crop rotation system under no-till system (NTS). This research was carried out from October 2010 to February 2014 in a Rhodic Hapludox. The experiment was set up in completely randomized blocks in a factorial design with eight cover crops and three soil depths (0-5, 5-10 and 10-20 cm) with four repetitions. Cover c...
